Why use a holder instead of tape or foam?
Ad hoc solutions using tape and foam have multiple issues. The net result is often a damaged or stuck battery.
Problems with Tape or Foam:
- They don't protect the delicate battery connection
- Tape or foam can shrink, causing the battery to fall out
- They can cause the battery to overheat
- Tape, especially, can fuse to the inside of the seat post
